CMX-309 series

FEATURES:

(1,000pcs/reel)

Being of the miniature plastic SMD type and featuring high efficiency

in mounting, the CMX-309 is ideal for application to high-density

circuit boards.

As it incorporates a heat-resisting packaged cylinder-type crystal, it

features highly stable characteristics-high enough to permit reflow

soldering.

Can be mounted automatically because of the emboss taping used.

Low power CMOS IC.

Provided with output enable function.

APPLICATIONS:

Can be used for a wide range of applications including use in

communication equipment, AV equipment, OA equipment and

measuring instruments.
